Well now I know what my next problem is!

I hear Carlos and the stud stretch. Here's how I would approach it. I'd measure my exposed head stud threads as far as who is stretched more than the others? If they clear as in equal height, my test is to spin the head nuts on next. Are they free sliding or do they hang as they spin on?

First few threads would hang up the turns, so this would mean both nut and studs are junk. If they spin on, that says no stretched studs or nut damage. Next part to think about is my [stretch] save of not loading the 90°. Add the crush to both gaskets [give] also keep that stretch at bay.

That says I am good to go, no stretch at the threads, nuts fly on, 90 sort of helped reuse the studs and nuts. Just for hee-hees, if I told you a guy slaps his engines together, does not us the same bolt or nut back into the same hole, etc., and the engines stay together under racing conditions, still beats the competition. So much for matching parts back together.

Are these what your talking about Carlos, http://www.feulingparts.com/category/Fasteners/Cylinder Studs And Head Bolts, they definitely are bad ass, I am getting different advise from a few people, some say not to worry about changing them and others say to change them, I am really liking these ARP studs, just a bit pricey for me right now, but I am pretty sure it's the right thing to do!
Whoa $350 for studs and bolts....wow that's expensive

I can't afford those so I am gonna just change them out with S&S new one's for $140.00 just for peace of mind!
I can't believe the different opinions on this!
I called the S&S tech this morning and he said I can re-use them no problem! Anyway, it's tore apart so I might as well change them out, better safe than sorry! Don't want to be doing this again!
I would never hear the end of it from you know who, ain't that right Wankers!

Do your own thing, that is what I did. I put on my big boy pants and said I am doing this with my engine build up. Those that say no don't use them are those you see riding on the shoulder of the road at 35 mph, full leather, helmet, flashing lights, highway bars, you name it they got it. Those that say yes have been there and back. I certainly have and in some cases I have forgotten more than others will ever know what is good and is not. But lets not go there, I am forgetting more every day, it comes with age :oldlaugh: :oldlaugh:

Carlos :whoop:

Should they both be a MLS type gasket? Is that the recommendation?


Always use the same style gaskets on BOTH cylinders.
Do NOT re-torque the mls gaskets.(Cometic, Cyco, Screamin Eagle, or others)!!!
Your head gasket WAS installed properly.
No need to change cylinder studs or head bolts. You'll do more damage to the threads in the case, if you change them very time you take the engine apart or heads off...
I use 40 ft. lbs. as my final head torque on all engines but S&S. I've pulled studs out of the case with anything over 42 ft. lbs. On S&S I use their head torque + 2 ft. lbs. on the 2 go rounds, and then go 90 degrees, mainly for any warranty issues.
I can't keep count of all the engines, and heads I do in a year. They all go together, without problems, and are long lasting with the specs I use above.

Hey Carlos, got any pics of the Buick? those were great cars.
I have mostly video of the cars. My ex took all of the photos, I'll have to check and see what I have as far as pictures is concern. My sons each had a Buick GN, the youngest had an 86 and the oldest had an 87. We did a little more tweaking to the 86 than the 87. The 86 ran a best of 10:80 at 116 mph. The 87 ran low 11's like 11:20 at about 109 mph. Then we stopped racing them as the parts or engines were no longer available. Cranks used to Break and we just kept them around till one got married and the other got tired of his 86 decided to sell his and the other followed within months. However we also had a 99 LS1 at the same time which we stroked 383 and punched it out to 4:125 which gave us a 409 Cu inches and shot it up with 250 NOS, 150 from the hole and 100 on the fly. Money was good back then so it didn't matter. That car ran a best of 10:001 at 135 mph, we had the mph to run a 9 something, but the track sucked so we never got it there. That car went with the Divorce LOL. I will try to post a video of what I have. After my Divorce I gave it all up and went back to Motorcycles, less expensive hobby, no slicks to buy every month and all that Racing fuel at $7.00 per gallon. BTW we did all the work on our cars except for the machine work, but cutting rings and assembly and overhauling Trannies we did it all. No more of that shit :oldbang: :oldnono:

Thanks Carlos, those were the good old days. Nothing like the smell of Turbo Blue racing gas.

Damn, I am confused now!
So if I understand you correctly John, your saying that my head gaskets were ok the way they were, even though the S&S instructions say to "install them with the wide side towards the cylinder" and that it would be worse to change the studs since I am taking a chance on screwing up the threads in the block! So basically everything was OK except the "final torque sequence" was not performed.
This thread has had more difference in opinion on any subject I have ever read on this site!
Very confusing to say the least, but I trust the guys that have the proven experience in building these engines, so I think I will reuse the studs and not chance screwing up the threads in the block.

Just finished getting it back together and it fired right up! This thing sounds and runs totally different with the 585 cam installed! So far, so good, well see how it goes, but I am sure that it was done right this time! And I did re-use the studs and bolts! Thanks everyone for your help and advise!

Your funny Frank!
Well, I am not sure yet, I just rode to the gas station and it says in the S&S manuel not to get on it for a while to let all the gaskets seat, so I believe I will find out today!
